Testing leads to failure, and failure leads to understanding

Science is not about consensus, and consensus is not science.

America was good enough to make a small compact lighter weight nuclear weapon. The Russians still had these big clunky heavy ones, so they had to build the big boosters in the arm's war, so now all of the sudden Russia could take off the shelf and put into orbit much heavier things than we could, so that's why they had the original leadership.

I spent about seven years during the Vietnam War flight-testing airplanes for the Air Force. And then I went in and I had a lot of fun building airplanes that people could build in their garages. And some 3,000 of those are flying. Of course, one of them is around-the-world Voyager.

Everything looks nonsensical before it works.

NASA is doing nothing but development. They're not doing research in manned spaceflight at all and I see no reason for them to do that because we already know that it will work and we already know exactly how it will work.

Virgin Galactic, which will be operating SpaceShipTwo, will be only one of several spacelines. The competitors for Virgin include the Russians, Bezos's Blue Origin, and possibly Rocketplane Kistler. And likely a couple of others who are smart enough not to tell people what they are doing!
